Roland,

You've the crux of the issue in "I miss moments". The kit lenses are
irrelevant. Get the right body & consider you lens choice as a sep decision.

No matter what body you move to, a product with a better value will come out
in 6 months or less. If you're satisfied with the performance you're getting
from your current camera, why not wait until something comes out at a
performance/value point that knocks your socks off?  I wouldn't bale out of
a system because I *thought* it *might* develop a dust problem.  The new
system *might* have one too, or *might* be defective out of the box, or just
*might* not work the way you'd hoped.

You can go broke chasing this technology.

Find a shop that will let you go outside (and maybe shoot a few inside with
and without a flash) and shoot some pictures on your OWN CF card, then have
prints made or make some at home and see if they look better than what you
have now. Then look at the features like no dust issues with the E300 or
the use of legacy lenses with the nikon or canon etc and decide for
yourself.

Other things to consider are, how easy it is to manually focus on the
supplied focus screen, do you like the control layout, are the
features/adjustments you'd most likely use often easy to adjust or are they
burried 3 menues deep, does it have DOF preview that's easy to use if you
like that feature etc etc. Think about what features you use most of the
time now and how it works on the replacement or what you hate about the old
one and if it's "fixed". Do you want to do a lot of low light shooting with
no flash? Then high ISO performance is important. If you think you'll be
changing lenses a lot in the field, the "dust buster" on the OM cameras
might be important to you. Some let you use the small on camera flip up
flash and a dedicated external, adjust the balance between the two using
one as a bounce and one as a fill, that's very handy and I use that
"feature" a lot.  Lots of things to think about that only you can decide
which ones are important to you.

Also look at the lens lineup and see if they have your needs covered or not.
You might not buy extra lenses now but might need to in the future. None of
the "kit" lenses perform as well as what the camera can produce with better
optics.

Each person has an answer for -themselves-, doesn't mean it's right for you.

why not the 350D ?

Roland,
  One thing to take into consideration, faster lenses are not always
better lenses, just faster.  Like the Nikkor 50/1.8D.  It is better than
the 3 times more expensive than the Nikkor 50/1.4D.  Now if you need to
shoot at f/1.4, then you need to, but faster is not always better, just
faster.  It takes far better glass and more complex systems to make a
faster lens, great.  So, the fact that the 18-70 kit lens is not as fast
as the e10 f/2 lens doesn't mean that much, unless you always shoot at
f/2.  But at f/5.6 I would put money on that 18-70 lens being just as
good, if not better than the E10 lens.  To answer your question.  The
D70, with a great lens is awesome.
